[FIX] data: _.find (prefered to older _.detect) may return undefined if no match and would trow an error when applying .values
Instead returns undefined which is handled below.
This does not solve the issue when records are not loaded properly but gives a better information on the reason.

Closing previously occured on search request (so that a user wouldn't be able
to select "old" data on new search request), but ``search`` is only triggered
after the search delay. Worked when delay was 0, with it being moved to 250 a
user can get results matching the previous search instead of the current one.

Trigger a closing of the current results list on any ``input`` event, which is
when text is entered in any of the searchview's ``InputView``
